Around Halloween, Five-0 stumbles onto several violent crimes apparently inspired by Hawaian native folklore (myth and legends). Steve stands by Alicia Brown, who confides into him before her trial she actually shot the serial killer mastermind, he advises to tell nobody and gets court permission to take her away, suspending the trial, to help investigate the presumably serial killings, incldingTyler Riggins who is found dead in his truck stranded on the old Pali Highway, midst wild boar tracks, and the recent murder of Bryon Hansen. Behind this pattern they find everything links to a girl's abduction and mutilation years ago, her return and a kid niece's kidnapping. In Florida, Grover speaks on death row to expert hitman Sebastian Wake, who offers prove he was hired by Clay Maxwell to murdering his wife fora stay of execution by electric chair.
